ADAS3022BSTZ

ADAS3022 is a complete 16bit, 1MSPS, successive approximation based analogue-to-digital data acquisition system, which is manufactured on Analog Devices, Inc., proprietary iCMOS® high voltage industrial process technology. This device integrates an 8-channel, low leakage multiplexer; a high impedance programmable gain instrumentation amplifier (PGIA)stage with high common-mode rejection; a precision, low drift 4.096V reference and buffer; and a 16-bit charge redistribution analogue-to-digital converter with successive approximation register (SAR) architecture. It can resolve eight single-ended inputs or four fully differential inputs upto ±24.576V when using ±15V supplies. In addition, the device can accept the commonly used bipolar differential, bipolar single-ended, pseudo bipolar, or pseudo unipolar input signals. It is used in application like multichannel data acquisition and system monitoring, process control, power line monitoring, automated test equipment, instrumentation.
